Help me pleaseeeeeeeeeeeeeeee

inn [45]

Answer:

1) n^2 – 3 n + 8 4^2 – 3*4 + 8 = 12

2) (x^2 – 4 y) / 2 (16 + 12) / 2 = 14

3) 4 * |-7 – 2| = 4 * 9 = 36 Abs -9 = 9

4) 19 – x^2 = 19 – 25 = -6 (-5)^2 = 25

5) S^2 t – 10 = -8^2 * ¾ -10 = 64 * ¾ - 10 = 38

6) 4 p^2 + 7 q^3 = 4 * 9 + 7 * (-8) = - 20 (-2)^3 = -8

The length of a rectangle is three times its width. If the area of the rectangle is 192 ft^2, find its perimeter

Blababa [14]

Answer: 64 feet.

Explanation:
Perimeter formula: 2l + 2w
Area formula: l•w
Length = 3w
Area = 192 ft $^{2}$
192 = (3w) • w
192 = 3 $w^{2}$
192 ÷ 3 = 3 $w^{2}$ ÷ 3
64 = $w^{2}$
$\sqrt{64}$ = $\sqrt{ w^{2} }$
8 = w

Width = 8
Length = 3(8) = 24
Perimeter = 2(24) + 2(8) = 64 feet.

egoroff_w [7]

Answer: <u>The 2 roads are 1.25 miles apart.</u>

Step-by-step explanation:

If 1 inch equals .25 miles, then you need to multiply .25 by 5.

Use proportions. Make sure the miles are on the same "side" of the fraction. Side meaning the top or the bottom

$\frac{1}{.25} =\frac{5}{x}$
